To all whom t may concern: V i

Be it known that I, WILLIAM l. KILLnEN,

a citizen of the United States, and resident of Washington, in the District of Columbia, 'have inventednew and useful Improvements in Concrete Floor Constructions, of which the following is a specification.

This invention relates to concrete floor construction and more 4particularly to a sleeper tie, which is used in the constructlon of concrete buildings.

The invention resides in a sleeper tie which is exceedingly durable, -cheap and 'easy to manufacture and the using,` of the tie results in a great saving of time and labor.

From .practical experiments it is to bel found that the use of the invention mate rially cheapens the cost of reinforced con- 'crete f loorings.

The invention further provides suitable means whereby the floor sleepers are ar ranged inthe upper portion ofthe concrete flooring to serve the purpose of guides for the top surface ofthe flooring, and to provide means forsecuring` the wooden flooring to the concrete construction.

The above and other objects and advan- 'tages of my improvement will fully appear from the following description taken in connection with the accompanying drawing and be explicitly defined in the appended claim.

I wish it understood, however, that this disclosure is illustrative only, and that the principleof vIn-y invention can be embodied in constructions other than the one specified herein. In the drawings, Figure 1 is a plan view of the sleeper tie;

Fig. 2 is a side View of the same; Fig. 3 is a vertical sectionalview through the concrete foundation; j A Fig. 4. is a similar view slrowing a modi fied forni ofthe sleeper tie; l

` Fig. 5 is a top View of the structure "shown in Fig. 3;

Fi g. 6 is a top view of the structure shown in Fig. 4;

Fig. 7 is a view showingmodified form of sleeper tie; and l Fig. 8 is a perspective View, showing how the sleeper tie secures the sleeper to the foundation. d

' Referring tothe drawings,.the numeral'lO shows a sleeper tie-which is preferably made et of cheap, durable material, such as lsheet metal or Wire. 0bviously,the tie can be stamped with a machine. cut by hand or made in other ways. Midway the length of said sleeper tie is shown a foundation or anchoring area ll, said area comprising` four tongues' l2, 13, lil, and l5. The object of thisfarea'is to enable the tie l0 to be securely held and anchored in the concrete, as will be more fully described later.

The metal tie l0 is embedded in concrete 16 before the concrete has become solidified. At, the level 17, two ends of the tie will project above. rllhesc ends may be bent parallel with the level 17 until used, the purpose of this bending being to prevent any one tripping or to prevent the ends from being broken ofi'. `lill/'hen it is desired to secure the sleeper 18 to the concrete floor, the sleeper 18 is placed between the ends of the tie. The ends of the tie are then bent to conform to 'the shape of the sleeper and may be secured to saidsleeperby several different means. Fig. 3 shows the metal ends nailed or otherwise secured to the sleeper. Fig. l shows, in addition to the ends of the tie being se cured to the sleeper, another securing means. The additional securing means resides in the Patented Apr. 23, rigid. l

extreme ends of the tie beingn bent. to extend outwardly from said sleeper into the cinder ller 20.

instead of the means of securing the Lie tothe sleeper as shown in Figs. 3 and Il, l have shown means of accomplishing this result by another modified form as shown in Fig. 7, ln this ligure, the nietahtie is of greater-length than the tie shown in Fig. 3

and the eXtreme endsl entend around the sleeper'and are secured to the top thereof b nails, screws or other securing; means. t will be seen that in this last "form, the tie. completely surrounds the sleeper and'rmly holds the sleeper in place, but the disadvantage of this form is thatthe tie may be observed.

' It is believed from the above description and operation that the construction of the invention is agmoarerlt.l lt is obvious that many modifications may be resorted to without departing from the spirit of 'the invention. For example, the shape of the several tongues 12to` 15 may 'be Widely varied and any conguration of the tongues or foundation area would suffice if the tie could be firmly intrenched in the concrete.

In reduction to practice, l have found that the form of my invention? illustrated in the drawings and referred te in the above de" uio l lllll) sciiptiim as the preferred Qnibodiinnn is tile most ciiicieiiii und pizicticaii, yet realizing than, the. conditions concurrent wiiii iii@ adoption of my device will necessarily vary, I desir-n to emphasize; the in@ 'that various minor changes in .aietaiis of Consti'ucion, proportion and arrangement of pniiis muy b sorted to, when required, withnut sacrificing any of the advantages of my invention as defined in the appended ciaini.

Having thus fuiiy described by invention what I cia'im and desire to secure by Mattei@ Patent, is:
